What reviewers say
“🇺🇸 This is a solid 3.8 for me, after a while opened showed itself round and nice. Floral nose with a hint of vanilla and cocoa butter, dark ruby, medium acidity, nice tannins, cedar, cherry, leather. Super QPR on promotion! Great daily wine.”
From a top-rated Vivino review for this bottle.
Summary
Intense red color with violet tones. Intense aroma dominated by fresh red berries such as strawberry and raspberry, where aromas from the barrel stage are also present. It has very soft and mature tannins, well wrapped in its body and volume.
Duorum Tons de Duorum Tinto is a Portuguese red from Douro. It sits in the under $15 band, on a lowest observed 750 ml price of $11.99. The blend is Touriga Nacional, Touriga Franca and Tinta Roriz.
Its in-cohort standing is measured against 350 other reds from Portugal, not against the corpus as a whole. The calibrated figure is built from 3,676 reviewers whose rating history varies enough to place their own average. A broader pool of 3,822 reviewers with two or more ratings feeds the raw-average track instead.
How the score was built
We compare the reviewers of this bottle against every other wine those same people reviewed. Each review is scored relative to the reviewer's own baseline — four stars from someone who hands out fives means something very different from four stars from someone who rarely goes above three. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.
- Global percentile
- Where Duorum Tons de Duorum Tinto lands against every wine we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — wines of the same type from the same country. A Chilean red is judged against Chilean reds, not against Champagne. Ranked against Red · Portugal (351 wines).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each wine keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 3,676.
